Like all other fields of human activities, Internet and web technologies have transformed education sectors as well. Technologies can play even larger role in accelerating this positive change.

Have a look at developed economies where the ratio of computers to students is one to one. Computing has already become an integral tool in all disciplines. Web based education software has matured and students and teachers are linked together. Computing in the classroom have gone much beyond students doing Internet searches, sending e-mail and checking spelling, presentation programs and spreadsheets; all useful and helpful aids for students as well as teachers.

Like all other technology optimists, I see Web technologies doing more than what they are doing in the class rooms presently. Parents can get more engaged and they can monitor their children’s attendance, punctuality, homework and performance, and can get tips for helping them at home. Teachers can share methods, lesson plans and online curriculum materials.

One of the best things is that computers can promote project based learning – a real advance from conventional textbook and lecture model of education. A project might begin with simple hypotheses. The shared Web space for the project, for example, would include the hypotheses, the sources the students must consult, their work plan and timetable, assignments for each student, the assessment criteria for their grades and, eventually, the paper the team delivers. Oral presentations may follow. The project-based learning encourages active learning and produces better performance in class and on standardized tests.

Happily, it has started happening; though only in developed world. This will follow in developing counties soon, one hopes.

These days, our mobile phones are really important to us that its hard to imagine life without them. However, they are a pretty new invention. this article traces the history of the mobile phone and questions what the future holds for it.

The mobile phone began life as the two way radio, which was also called mobile rigs. these were put in vehicles including taxis, police cars & ambulances, although were not strictly mobile phones because they weren’t normally connected to the telephone network. whereas the earliest mobile phones were permanently installed in vehicles, later versions including the transportables, also called bag phones, could also be carried, & can be used as portable or mobile two way radios.

The very earliest mobile phones were called first generation phones, also known as 1g. The 1g reign lasted from the late 1970s through to the 1980s. these devices were the very first real mobile phones, although they were then known as cellular mobile radio telephones, & were based on analogue signalling. the use of an analogue signal was the difference between these first generation mobile phones & their second generation cousins, which was released a few years later.

The very earliest second generation mobile telephones were commercially launched in finland in 1991. While 2g networks were fully digital, the earlier 1g networks were analog. one of the main benefits that 2g networks had over their 1-g predecessors was that phone conversations were digitally encrypted. This was big because third parties could to eavesdrop on calls on analog networks. as well as this, 2g systems were significantly more efficient, which allowed far more mobile telephones to be used. Finally, 2g introduced data services for mobile, including sms text messages.

After the launch of 2-g mobile phones, the previous mobile phone systems were dubbed 1-g. while radio signals on 1-g networks are analog, & on 2g networks they are digital, both the 1g and 2g systems use digital signaling to connect the radio towers & the rest of the phone system.

The earliest pre commercial 3g mobile telephone network was launched in japan in may of 2001. 3-g was later commercially released in Japan on october, 1 2001.

3g is the third generation of mobile phone standards and technology, which succeeded 2g mobile phone technology. the arrival of 3g technologies enabled network operators such as orange to offer their users a larger range of high-tech services. This includes broadband internet, in addition to high tech video calls.

Despite the success of 3g, there’s also been a number of complaints about it. These include criticism over the expense of 3g phones, a lack of network coverage because it’s still a relatively new service and the amount of power that 3g phones use.

Following 3g, we can get excited about the arrival of 4-g technology, which promises to be the best and most advanced mobile phone technology to date.

Thanks for browsing our article about the invention of the mobile phone. as you have probably realised, the mobile phone has come a long way since it was first launched and chances are, it will be developed further still.
